Semi-tethered jailbreak is already available for some devices for both iOS 5 and iOS 5.0.1. But we all want untethered jailbreak and we want jailbreak for iPad 2 and iPhone 4S. So why not help hackers to find new exploits and vulnerabilities?
The Chronic Dev-Team has a released a tool to collect crash reports from iOS devices in order to find vulnerabilities that could lead to an untethered jailbreak.
The idea is very simple. When your iPhone, iPad or iPod Touch crashes it sends data to Apple (you can turn it this off though). Apple uses these reports to update iOS in the future. By the way, it also uses them to fix exploits found by jailbreakers. P0sixninja says that Apple closed several exploits they have found in IOS 5 beta before the final version of the software was released.
In order to find more vulnerabilities as fast as possible, the team has developed a tool which will copy the crash reports from your device and analyze them to locate potential exploits. The tool will also remove the crash reports from your device and modify your iTunes installation to prevent uploading of that diagnostic information to Apple.
iH8Sn0w has released Sn0wBreeze 2.8b10. Here is a changelog:
Supports iOS 5.0 (9A334)/5.0.1-b2 (9A404)
Fixed iBooks sandbox crashing issues.
Fixed location services issues with iPhone 3GS users running the iPad baseband (06.15).
Re-added iPad baseband (06.15) install option to iPhone 3GS.
Removes UDID requirement/Beta timer in 5.0.1.
Tethered devices are booted via iBooty which is extracted to the Desktop after running sn0wbreeze.
As usual the jailbreak is semi-tethered for iPhone 4, iPad, iPhone 3GS with new bootrom, iPad Touch 3G, iPod Touch 4G and untethered for iPhone 3GS with old bootrom.
RedSn0w 0.9.9b8 recognizes 5.0.1 beta and you don’t have to “point at 5.0 IPSW” any more. Since the IPSW isn’t public, you’ll still need to provide it once to redsn0w (Extra -> Select IPSW).
Mac users can also create custom firmware and preserve baseband for unlock. However ultrasn0w doesn’t get updated for betas yet.
This is still a tethered jailbreak for all except old-bootrom 3GS users.
UPDATE: Apple latest firmware is iOS 5.1.1. Apple has stopped signing all other firmwares, including iOS 5.0.1, iOS 4.3.3 and iOS 4.3.5. This means you can NOT restore to 5.0.1/4.3.3/4.3.5 any more (both original and custom), unless you have saved your SHSH keys for it.
If you have decided to perform an untethered jailbreak and unlock, you need to get the following information:
What type of device do you have (iPhone 3G/3GS/4, iPod Touch 3G/4G, iPad 1/2, Apple TV)?
Do you need unlock (if your iPhone locked to one carrier and you want to use it with another)?
The answer is NO, if the device is not iPhone, if it was purchased as factory unlocked and can be used with any cellular carrier (f.e. in Canada, France, etc).
If the answer is YES, you need to find out your modem version (Setting-General-About-Modem).
What firmware version do you have? Take a look at Setting-General-About-Version. For example it could be iOS 4.3.3.
What operating system do you use on your desktop (Windows, Mac OS)?
How to perform jailbreak, when you do NOT need an unlock
For iPhone 3G the latest is iOS 4.2.1. You can perform jailbreak with any utility. For iOS 4.2.1 you can also use them or GreenPois0n (Windows, Mac OS).
iPad 2 jailbreak is available only for iOS 4.3.3 via JailbreakMe and and iOS 5.0.1 via Absenthe.
iPhone 4S jailbreak is available for iOS 5.0 / iOS 5.0.1 via Absenthe.
iOS 4.3.3
Apple stopped signing iOS 4.3.3, so you cannot update to iOS 4.3.3 without SHSH keys saved (in advance some time ago). If you have iPhone 4, iPhone 3GS, iPad 1, iPod Touch 3G or iPod Touch 4G that run iOS 4.3.3 – use JailbreakMe or RedSn0w to untether jailbreak your device.
If you have saved SHSH keys for iOS 4.3.3 you can use PwnageTool (Mac OS) or Sn0wBreeze (Windows).
iOS 4.3.4/4.3.5
For iOS 4.3.4/4.3.5 only tethered jailbreak is possible with redsn0w. Tethered means that each time you restart your device you will have to connect it to a computer and run redsn0w. The untethered iOS 4.3.5 jailbreak is possible only for iPhone 3GS with old bootrom. You can detect your bootrom version using this tutorial.
iOS 5
To jailbreak and unlock iOS 5 use latest version of redsn0w 0.9.9 or sn0wbreeze 2.8. You can jailbreak tethered or semi-tethered.
The untethered iOS 5 jailbreak is possible only for iPhone 3GS with old bootrom. You can detect your bootrom version using this tutorial.
iOS 5.0.1
For iPhone 4/3GS, iPad 1, iPod Touch 3G/4G an untethered jailbreak is available for iOS 5.0.1. For untethered jailbreak use the latest redsn0w 0.9.10 or Corona – package from Cydia to untether currently installed tethered jailbreak.
Tutorial how to untether installed tethered jailbreak is available here.
For iPhone 4S and iPad 2 use Absenthe.
For tethered iOS 5.0.1 jailbreak you an use redsn0w 0.9.9 and sn0wbreeze 2.8.
iOS 5.1 / iOS 5.1.1
For now only tethered jailbreak is available for iPhone 4/3GS, iPad 1 and iPod Touch 3G/4G for iOS 5.1 and iOS 5.1.1.
uses DFU mode to try to automatically determine which device and FW you have
fetches pieces of public IPSWs from Apple (once). Non-public IPSWs must be provided manually (once). It then caches those pieces for future use.
“Just boot” is a tethered boot. Uses whatever “Preferences” you’ve set for boot logo and kernel boot-args
“Pwned DFU” puts your device in a pwned DFU state for some of the iTunes stuff detailed below
“Recovery fix” gets past 1015 types of errors (when baseband portion of restore fails). Should work on iOS5 beta too
“Select IPSW” is for picking non-public IPSWs, or overriding auto-detection
“SHSH blobs” has a bunch of options…
“Fetch” – fetch current PARTIAL blobs on device. Should complete in under 10 or 15 seconds. Puts the set of PARTIAL of blobs on your computer as a plist. Checks if Cydia already has a full set for this device and build. If not, it submits this PARTIAL set and returns Cydia’s acknowledgement or rejection
“Verify” – cryptographically verifies existing blob files from either redsn0w, TinyUmbrella, or Cydia server. You can select a whole bunch of blobs to verify at once if you want (like the TinyUmbrella directory)
“Submit” – both verifies and submits one or more blob files to Cydia. This lets you copy your entire TinyUmbrella cache of blobs up to the Cydia server
“Query” - queries the Cydia server for all available FULL or PARTIAL blobs for a given set of ECIDs
“Stitch” – stitches either FULL or PARTIAL blobs to a STOCK or CUSTOM IPSW
Stitching is NOT yet supported on iPhones! Need to work out the baseband part of the restore process.
FULL blobs stitched to a STOCK IPSW gives you a completely self-contained signed IPSW that iTunes will accept without any tricks (no need to go into pwned DFU mode, no need to start TinyUmbrella TSS server, no need to redirect to Cydia server for blobs)
PARTIAL blobs stitched to any IPSW requires you to go into pwned DFU mode before running iTunes. No need to start TU or use Cydia though.
Stitching either FULL or PARTIAL blobs to a CUSTOM IPSW also requires a pwned DFU start before iTunes restores. No need to start TU or use Cydia though./li>
Will eventually support fetching the blobs directly from Cydia instead of a file on your computer
untethered jailbreak for iPhone 3GS with old bootrom (iOS 4.3.5 or iOS 5 Beta 7)
Musclenerd posted via twitter:
New redsn0w is.gd/6eek4Y explicitly supports iOS5b7 (no need to point at b6 IPSW). Also brings back old-bootrom 3GS goodies.
This is great news for both developers and owners of old bootrom iPhone 3GS’s who accidentally updated to iOS 4.3.5.
DevTeam posted:
About 12 hours after we released redsn0w 0.9.8b7 with some improvements for iOS5b6, Apple went and released iOS5b7 (what are the odds of that?!?). Even though that redsn0w could still jailbreak iOS5b7, you needed to point it at the iOS5b6 IPSW to do so. Today’s redsn0w 0.9.8b7b lets you point redsn0w directly at the iOS5b7 IPSW instead.
We’ve also added some overall improvements for old-bootrom 3GS owners (where the 24kpwn exploit applies): on those devices, you can tell redsn0w to untether 4.3.5 and lower, or iOS5b7. Old-bootrom 3GS owners can once again choose custom logos, and/or verbose booting (for the really nerdy iPhone3GS fans out there!). And it allows 4.3.4 or 4.3.5 users to use ultrasn0w again (if they have a compatible baseband).
Last but not least, we fixed some lingering Verizon iPhone4 4.2.10 JB issues.
iH8Sn0w released Sn0wBreeze 2.8b7, which adds jailbreak support for the latest iOS 5 beta 7 firmware.
Sn0wBreeze creates custom firmware and allows users to preserve baseband for unlock (ultrasn0w doesn’t work with iOS 5 yet). This new version also adds hacktivation and removes UDID developer check. This means that you can try iOS 5 without developer account from Apple.
You can download Sn0wBreeze 2.8b7 for Windows here.
